/**
 * 核心原理
 * 1）、@EnableRedisHttpSession导入RedisHttpSessionConfiguration配置
 *      1、给容器中添加了一个组件
 *          SessionRepository=>>>【RedisOperationsSessionRepository】：Redis操作session，session的增删改查封装类
 *      2、SessionRepositoryFilter==>Filter:  sessoin 存储过滤器，每个请求过来都必须经过filter
 *          1、创建的时候，就自动从容器中获取到了SessionRepository
 *          2、原始的request和response都被包装。SessionRepositoryRequestWrapper，SessionRepositoryResponseWrapper
 *          3、以后获取session。request.getSeeion()
 *          4、warppedRequest.getSession();==>SessionRepository 中获取的
 *  自动延期；redis中的数据也是有过期时间的
